SME v5.6
"Server Only" mode, inside a LAN behind a firewall.
I am trying to exercise the email services of the SME server from a client within the LAN. Client is MacOS X 10.2.4 using the Apple Mail app.
I have set up the client:
POP: mail.192.168.10.1
SMTP: mail.192.168.10.1
This is only for testing. Once I am confident with how it works, I will use a normal "mail.mydomain.com" form.
When attempt to send mail, I get an error message "The server cannot be contacted on port 25" or the mail just sits in the "out box" of the client and never "leaves".
A port scan of the SME machine indicates port 25 is open. Port 25 in the firewall is closed, but I assume that doesn't have any bearing as both the SME server and client are inside the firewall.
As you can probably tell, I don't know anything about the email server's operation, so any info, links or suggestions are welcome.
